Abstract

L'invention concerne une lentille ophthalmique destinée à générer une pluralité de foyers et pourvue d'un système optique comprenant une surface antérieure, une surface postérieure et un axe optique. Ce système optique comprend une première zone et une seconde zone. La première zone possède une puissance optique de réfraction et comprend une plaque à phase multifocale de formation d'un premier foyer et d'un deuxième foyer. La seconde zone possède une puissance optique de réfraction et comprend une plaque à phase monofocale de formation d'un troisième foyer. La plaque à phase multifocale et la plaque à phase monofocale peuvent être disposées, respectivement, sur une première et une deuxième courbure de base pouvant présenter différents rayons de courbure. La lentille ophtalmique peut également comprendre une phase intermédiaire située entre la plaque à phase multifocale et la plaque à phase monofocale, la plaque à phase intermédiaire comprenant une troisième pluralité d'échelettes disposées sur une troisième courbure de base présentant un troisième rayon de courbure.
